Technical Questions


Q:
What is Java 2 Platform, Standard Edition (J2SE platform)?
A:
The J2SE platform is the set of Java technologies that delivers to developers the primary value proposition of Java technology- "Write Once, Run Anywhere". It provides a layer of abstraction between the developer and the native (OS) platform libraries and utilities so that Java code can be developed to a single specification but deployed to a variety of operating system environments.

The J2SE platform comprises the Java 2 runtime environment, development tools and APIs. The Java 2 SDK (Software Development Kit) includes both the Java 2 runtime environment and the Development Tools and APIs.

For Solaris Operating System (OS) customers, Sun's recommended starting point is the web site for Java technologies for the Solaris platform: http://www.sun.com/solaris/java. For more information on J2SE platform technologies, please visit the official J2SE technology website: http://java.sun.com/j2se

Q:
Why is the J2SE 1.4 platform so much better than previous releases of the J2SE platform?
A:
J2SE 1.4 delivers feature enhancements that enable better performance, tighter security, and improved serviceability of Java deployments.
  • 64-bit Support: Combined with the Java HotSpot Server VM code optimizer and existing 64-bit support in the Solaris OS, improves Java servlet performance, enables greater number of concurrent network connections, improves IO performance through the new IO package, provides access to larger memory space, and improves overall performance from prior J2SE releases.
  • Enhanced Security: Java GSS-API with Kerberos support, Java Secure Socket Extension (JSSE), Java Cryptography Extension (JCE) and other security enhancements enable developers to implement high levels of security in their Java code.
  • RAS (Reliability, Availability, Serviceability): Variety of feature enhancements that improve RAS (Reliability, Availability, Serviceability) including improved logging and assert mechanisms.

Q:
Why is running the J2SE 1.4 platform on the Solaris 9 OS better than running on other platforms?
A:
It is the combination of the world class J2SE 1.4 platform and the Solaris 9 OS that makes J2SE software on the Solaris platform one of the best integrated platforms for running Java applications of the future. As the previous question explains, J2SE software provides a multitude of features that can be leveraged by Java developers and systems administrators.
